Requirements

The amount of each requirement may fluctuate from country to country based on the wealth of the country.

The funds are 'reserved' at the moment the law is proposed and they are visually removed from the country accounts. Then if the law fails they are returned. If the law passes the founds are completely removed.

The airstrike laws can proposed only once every 14 days, but only accepted laws are taken into consideration; so, if an airstrike law is rejected by congress, another one can be proposed in less than 14 days.

Each citizen above level 25 can contribute to the airstrike requirements by donating currency or food.
